'Molding' in the Bible

Now and then there would be something wrong with the pot he was molding from the clay with his hands. So he would rework the clay into another kind of pot as he saw fit.

Concerning the pillars, the height of each pillar was eighteen cubits (twenty-seven feet), and a line [an ornamental molding] of twelve cubits (eighteen feet) went around its circumference; it was four fingers thick, and [the pillar was] hollow.
